When four professional criminals break into a Barrington Hills mansion expecting an easy score, they tie up oil heir Edward Pike and his wife and demand access to a hidden fortune. When Edward doesn't break fast enough, they kill her to send a message.

They have no idea who just lost his temper.

Edward Pike has spent thirty years perfecting a private ritual the FBI knows only as "the Auditor" — a killer who finds what the system missed and delivers his own brand of justice, one victim at a time, without ever leaving a trace. Now his house has become a locked box, and the four men who broke into it are about to learn exactly what they walked into.

As bodies fall one by one, one man in the crew refuses to run — and three hundred miles away, the federal agent who's hunted the Auditor for six years finally catches his trail. But some hunters get away. And some houses remember everything.
